How much battery would drain an Android service with BroadcastReceiver

Lets put the following service in as an example:

public class MyService extends Service {

    final BroadcastReceiver mScreenStateReceiver = new BroadcastReceiver() {
        @Override public void onReceive(Context context, Intent intent) {
            //Do nothing
        }
    };

    @Override
    public void onCreate() {
        super.onCreate();
        IntentFilter intentFilter = new IntentFilter();
        intentFilter.addAction(Intent.ACTION_SCREEN_OFF);
        intentFilter.addAction(Intent.ACTION_SCREEN_ON);
        registerReceiver(mScreenStateReceiver, intentFilter);
    }

    @Override
    public void onDestroy() {
        super.onDestroy();
        unregisterReceiver(mScreenStateReceiver);
    }

}

Note that THIS BroadcastReceiver requires being registered at RUNTIME (lets say, Service or Activity). That is the reason I am using a Service

Supposing that this Service is going to be running the whole time the device is turned on, have a working BroadcastReceiver and is doing nothing, would it drain battery life? If it would, how much? Can make it running make the Android framework drain more battery due to have a Service or Broadcast Receiver running?

I know, I am a battery life maniac

A BroadcastReciever itself does not consume much battery. The task that you do inside it decides how much battery is drained. Refer this and this.
